更换 SFP 后， NIC 仍会发现 CRC 错误
适用场景
- AFF A400
- 10G/25G 以太网端口
e0g/e0h - SFP 更换
- LC 光缆
问题描述
- 中显示的端口联机
sysconfig -a
::> run -node <node_name> -command sysconfig -a slot 0: 10G/25G Ethernet Controller CX5-Mezz e0g MAC Address: d0:39:ea:xx:xx:xx(auto-10g_sr-fd-up) SFP Vendor: FINISAR CORP. SFP Part Number: FTLX8574D3BCL SFP Serial Number: xxx e0h MAC Address: d0:39:ea:xx:xx:xx (auto-10g_sr-fd-up) SFP Vendor: FINISAR CORP. SFP Part Number: FTLX8574D3BCL SFP Serial Number: xxx Device Type: CX5 PSID(NAP0000000007) Firmware Version: 16.26.4012
- 存储端口上的 SFP 最近已更换
ifstat即使更换 SFP 后，受影响端口上的 CRC 错误也会增加
::> run -node <node_name> -command ifstat -- interface e0g (7 hours, 33 minutes, 13 seconds) --
